Grain‐filling response of winter wheat (Triticum aestivum L.) to post‐anthesis shading in a humid climate

To assess the impacts of clouds during the grain‐filling period on the leaf senescence and yield of wheat ( Triticum aestivum L.), we conducted a 4‐year plot shading experiment in a well‐drained Andosol in northern Japan. Plants were shaded after the beginning of anthesis in mid‐June, which corresponds to a naturally cloudy period in the study region. The effect of shading depended on its synchronization with soil drying, which affected leaf...
